[rtl] DMA (latencies and jitter)

[Giovanni Racciu]

It is a matter of fact that heavy DMA can affect (increasing) latencies and jitter. In our actual solution the software is running on a dedicated PC104 board, which is not corrupting the latency. But as a future develpment we would like to put it on a standard PCboard and the entire Linux OS plus the applications will run on it (using all the hardware features in a massive way). Is there anybody who has an idea on how big (worst case) could be the increasing latency and gitter ?   Thank you.   Ciao Giovanni Racciu
